Serial Port configuration

AlaMode can communicate via the UART pins of the GPIO connector. Unfortunately, for now, the Arduino IDE doesn’t recognize the device name /dev/ttyAMA0, so you’ll need to create an alias. By the way, it also doesn’t recognize the Arduino UNO (/dev/ttyACM0) so you can handle this the same way.

deleting the two parameters involving the serial port /dev/ttyAM0
You also have to edit /etc/innitab to remove the login (getty)

Reboot

Installing the Arduino IDE

Before getting any of the other packages:

[code]sudo apt-get update[/code]

and again:

[code]sudo apt-get update[/code]

The IDE is written in Java (based on Processing) and while Oracle doesn’t have an official Java for the ARM core in the Pi, the Open JDK has been ported. It doesn’t have a JIT (Just In Time Compiler) so it’s a little slower, but it works.
First grab the Arduino IDE code. 1.01 is heavily entwined with the native GCC toolchain, so is a lot more work and not recommended. For now, stick with 1.0.
